Bravo Betallaluz, Stefani Valeria, Chambilla Benito, Sly Sofía, Camacllanqui Ruiz, Grecia Victoria, Perez Pacori, Grecia De Los Ángeles, Gonzales Legario, Arlath Nayli 21 July 2020 (has links)
En la actualidad, los usuarios de cuentas premium en plataformas de streaming suelen buscar con quien compartir sus cuentas para ahorrar en costos, sin embargo, no encuentran las personas indicadas para compartir el servicio, o si ya pertenecen a un grupo una problemática común es que los demás usuarios se demoren en pagar sus cuotas, generando incomodidad, estrés y peleas entre todos los miembros. Nuestro proyecto se hizo con la finalidad de desarrollar un servicio que soluciona la problemática de los usuarios de plataformas streaming. Por tales motivos ofrecemos una solución que es Cuenta Plus, una plataforma que reúne los requisitos más solicitados por el público objetivo determinado y que se adapta a las necesidades de los clientes de la era digital que son cada vez más exigentes. Asimismo, la plataforma ofrece una opción formal y segura a los clientes y de esta manera compite directamente con las ofertas informales y limitadas que existen en el mercado. En el desarrollo del proyecto se determinó el modelo de negocio, el público objetivo, las proyecciones de crecimiento de la empresa, los costos en los que se debe incurrir, las utilidades, el valor del negocio, entre otros aspectos, necesarios para la viabilidad de la empresa Cuenta Plus. / "Nowadays, Premium account users on streaming platforms often search with whom to share their accounts to save on costs, however, they do not find the right people to share the service, or if they already belong to a group, a common problem is that other users delay in paying their dues, generating discomfort, stress and fights among all the members. Our project was made in order to develop a service that solves the problems of streaming platform users. For these reasons we offer a solution, Cuenta plus, a platform that meets the requirements most requested by the determined target audience and that adapts to the needs of customers in the digital age, who are increasingly demanding. Furthermore, the platform offers a formal and secure option to clients and thereby competes directly with the informal and limited offers that exist in the market. In the development of this project many subjcts were determined: the business model, the target audience, the growth projections of the company, the costs to be incurred, the profits, the value of the business, among other aspects, necessary for the viability of the company Cuenta plus." / Trabajo de investigación

An investigation of performance versus security in cognitive radio networks with supporting cloud platforms

Irianto, K.D., Kouvatsos, Demetres D. January 2014 (has links)
No / The growth of wireless devices affects the availability of limited frequencies or spectrum bands as it has been known that spectrum bands are a natural resource that cannot be added. Meanwhile, the licensed frequencies are idle most of the time. Cognitive radio is one of the solutions to solve those problems. Cognitive radio is a promising technology that allows the unlicensed users known as secondary users (SUs) to access licensed bands without making interference to licensed users or primary users (PUs). As cloud computing has become popular in recent years, cognitive radio networks (CRNs) can be integrated with cloud platform. One of the important issues in CRNs is security. It becomes a problem since CRNs use radio frequencies as a medium for transmitting and CRNs share the same issues with wireless communication systems. Another critical issue in CRNs is performance. Security has adverse effect to performance and there are trade-offs between them. The goal of this paper is to investigate the performance related to security trade-off in CRNs with supporting cloud platforms. Furthermore, Queuing Network Models with preemptive resume and preemptive repeat identical priority are applied in this project to measure the impact of security to performance in CRNs with or without cloud platform. The generalized exponential (GE) type distribution is used to reflect the bursty inter-arrival and service times at the servers. The results show that the best performance is obtained when security is disabled and cloud platform is enabled.

ESSAYS ON ONLINE IDENTITY DISCLOSURE AND DISCOVERY

Kwon, Youngjin, 0000-0002-0795-9578 08 1900 (has links)
With many kinds of personal information becoming available online in the past decades, this dissertation addresses the personal, managerial, and societal implications of personal information online that used to be private in the past. Essay One (Chapter 2) investigates the role of social information (such as names and profile photos) in racial discrimination against Blacks using a correspondence method on an online rental housing platform. It examines whether Blacks with non-Black-sounding names are discriminated against, compared to those with Black-sounding names or Whites, when race is signaled through profile photos. In addition, it studies whether building less complete profiles (e.g., using pseudonyms or not presenting profile photos) impartially hurts Blacks and Whites. Essay Two (Chapter 3) compares involuntary discovery and voluntary disclosure of personal information (invisible stigma) in a hiring context. It examines how the two modes of learning about job applicants’ social media differently influence hiring outcomes. Essay Three (Chapter 4) looks at party identity as antecedents of online privacy decisions for public safety such as personal data for contact tracing and crime detection. Additionally, it investigates two interventions that promote online privacy decisions for public safety when party identity is salient: deemphasis on party identity and recategorization as national identity. Overall, this dissertation contributes to the literature on information systems, social psychology, and economics by highlighting the role of digital technology in enabling a greater depth of identity disclosure and discovery and thus changing the landscape of perception and decision-making today. / Business Administration/Management Information Systems

Misinformation as a Negative Externality : Theory to Remedy

Cattich, Ryan January 2022 (has links)
In the wake of events like the COVID-19 pandemic, the storming of the Capitol, and the Russian invasion of Ukraine, it’s time to start labeling misinformation for what it is: a negative externality to society. The spillover effects from the proliferation of mis- and disinformation have the potential to negatively impact the institution of democracy, civic engagement, and downstream health outcomes. Put simply, to understand the misinformation problem is to understand its complexities, its pitfalls, and its motivations. Taken as a whole, this paper articulates the need for a divergence from conventional economic theory on efficiency to a pro-social, welfare-based approach to internalization efforts. In doing so, this analysis presents a full-scale characterization of misinformation as a negative externality, starting with the reorganization of traditional microeconomic theory, followed by a platform-by-platform evaluation of various internalization strategies and evidence from the literature on the impacts of misinformation, and concluding with a commentary on potential remediation approaches. / Thesis ( BA ) — Boston College, 2022 . / Submitted to: Boston College.

Transparency and Movement in Architecture

Estremadoyro, Veronica 27 August 2008 (has links)
This project investigates transparency and movement as the main measured elements that define space. These elements seek to articulate distinct and memorable places throughout the building, acknowledging its unique setting along the Potomac River in Old Town Alexandria, Virginia. Architecture and nature as opposite elements combine here to define a building in which water, light and views become the main architectural agents set in dialog with the natural surroundings. An existing boardwalk along the levee transforms into a transparent enclosed space that connects both city and water on opposite sides. Programmatically a series platforms, walls and volumes are inhabited by a cultural center. The cultural center contributes to the artistic spirit and identity of the city by concentrating various artistic representations. / Master of Architecture

ProduÃÃo acadÃmica brasileira em contabilidade de custos aplicada ao setor pÃblico: plataformas teÃrico metodolÃgicas e aspectos normativos / Brazilian academic production cost accounting applied to the public sector: methodological theoretical platforms and normative aspects

Cicero Philip Soares do Nascimento 29 August 2013 (has links)
CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / A contabilidade de custos aplicada ao setor pÃblico apresenta-se diante de grandes desafios com o advento das diretrizes para a estruturaÃÃo do sistema de informaÃÃo de custos do setor pÃblico. Tais diretrizes normativas, impulsionadas pelas normas brasileiras de contabilidade aplicadas ao setor pÃblico, possibilitam melhorias na qualidade informacional das informaÃÃes de custos no setor pÃblico. Paralelamente, diante do cenÃrio de potencias mudanÃas da contabilidade de custos aplicada ao setor pÃblico, surge o questionamento acerca do estÃgio teÃrico-metodolÃgico da Ãrea, considerando haver a necessidade de ampliaÃÃo das discussÃes acerca de conceitos e bases teÃricas demandadas pelo contexto de mudanÃas. Diante deste cenÃrio, o objetivo do presente estudo consiste em analisar as plataformas teÃrico-metodolÃgicas da produÃÃo acadÃmica brasileira em contabilidade de custos aplicada ao setor pÃblico, considerando os aspectos normativos que regem essa temÃtica. O estudo adota uma abordagem mista, compreendendo a combinaÃÃo de elementos qualitativos na coleta por meio da anÃlise de conteÃdo, e quantitativos, evidenciados por meio da estatÃstica descritiva. Trata-se de um estudo descritivo, tendo a pesquisa documental como principal estratÃgia utilizada. Identificou-se 21 Programas de PÃs-graduaÃÃo stricto sensu da Ãrea de contabilidade como ambiente depositÃrio dos produtos intelectuais produzidos, notadamente as teses e dissertaÃÃes, bem como 18 periÃdicos que mantÃm relaÃÃo com estes programas, analisados no perÃodo de 2003 a 2013. Os resultados revelam que apenas 47 trabalhos tratam da contabilidade de custos aplicada ao setor pÃblico, enquanto 295 tratam da contabilidade de custos aplicada ao setor privado. Observou-se declÃnio da produÃÃo cientÃfica a partir do final da dÃcada de 2000. Quanto Ãs plataformas teÃricas, observou-se pouca utilizaÃÃo de modelos teÃricos que fundamentem as pesquisas, sinalizando que o foco nÃo està em predizer ou explicar os fenÃmenos, mas descrevÃ-los; grande Ãnfase na utilizaÃÃo de autores que tratam da contabilidade de custos no setor privado, nÃo existindo o desenvolvimento ou disseminaÃÃo de uma literatura genuÃna para a Ãrea; e temas centrados em ambientes hospitalares ou universitÃrios. Quanto Ãs plataformas metodolÃgicas, verificou-se possuÃrem abordagem qualitativa, descritiva e exploratÃria; utilizarem como estratÃgias de pesquisa o estudo de caso, a pesquisa documental e bibliogrÃfica; adotarem a pesquisa documental, a entrevista e o questionÃrio como principais tÃcnicas de coleta; e analisarem os dados por meio da estatÃstica descritiva. Quanto aos aspectos normativos relativos à Norma Brasileira de Contabilidade Aplicada ao Setor PÃblico - NBCT 16.11, observou-se que o valor da informaÃÃo de custos centra-se em fins gerenciais; o objetivo de um sistema de informaÃÃo de custos està focado em apoiar a tomada de decisÃo dos processos; e o Custeio Baseado em Atividades constitui o principal mÃtodo de custeio estudado pela academia. Ao tÃrmino, foi possÃvel concluir que as plataformas teÃrico-metodolÃgicas da produÃÃo acadÃmica brasileira em contabilidade de custos aplicada ao setor pÃblico desenvolvem-se com arcabouÃo teÃrico ainda incipiente e desprovido de identidade particular capaz de retratar os fenÃmenos observados nas organizaÃÃes pÃblicas frente Ãs mudanÃas, alÃm das abordagens metodolÃgicas ancoradas no paradigma fenomenolÃgico. / Cost accounting applied to the public sector presents great challenges before the advent of guidelines for the structuring of the information cost of the public sector system. Such regulatory guidelines, driven by Brazilian accounting standards applied to the public sector, enable improvements in information quality of information costs in the public sector. Meanwhile, on the potential changes of accounting applied to the public sector cost scenario, the questioning about the theoretical and methodological stage area arises, considering there is a need to expand the discussion about concepts and theoretical bases of change demanded by the context. In this scenario, the objective of this study is to examine the theoretical and methodological platforms Brazilian academic production accounting applied to the public sector costs, considering the regulatory aspects governing this issue. The study adopts a mixed approach, comprising the combination of qualitative elements in the collection by means of content analysis, and quantitative, as evidenced by descriptive statistics. This is a descriptive study, and documentary research as the main strategy used. We identified 21 programs Postgraduate stricto sensu the accounting field as depositary environment of intellectual products produced, especially theses and dissertations, as well as 18 journals that maintain a relationship with these programs analyzed in the period 2003-2013. Results show that only 47 papers deal of cost accounting applied to the public sector, while 295 deal with the accounting applied to private sector costs. Observed decline of scientific production from the late 2000s. Regard to theoretical platforms, there was little use of theoretical models that support research, signaling that the focus is not to predict or explain phenomena but describe them; great emphasis on the use of authors who treat of cost accounting in the private sector, with no development or dissemination of literature to a genuine area; and themes focused on hospital or university settings. As for the methodological platforms, it was found possessing qualitative, descriptive and exploratory approach; use strategies for the case study research, documentary and bibliographic research; adopt the document research, interview and questionnaire as the main data collection techniques; and analyze the data using descriptive statistics. As for the regulatory aspects of the Brazilian Standard Applied to the Public Sector Accounting - NBCT 16:11, it was observed that the value of cost information focuses on managerial purposes; the objective of an information system cost is focused on supporting the decision making processes; and Activity Based Costing is the main method of costing studied by academia. At the end, we concluded that the theoretical and methodological platforms Brazilian academic production cost accounting applied to the public sector develop with particular incipient and devoid of identity theoretical framework capable of portraying the phenomena observed in public organizations to the changes, besides the methodological approaches grounded in the phenomenological paradigm.
